摘要:

旨在建立乌骨鸡黑色素细胞体外培养和鉴定的方法,为研究黑色素细胞功能提供理想的生物材料。本研究选取乌骨鸡腹膜组织,采用DispaseⅡ和胰酶-EDTA混合消化法,经严格控制不同培养阶段的消化时间,对黑色素细胞进行纯化和传代,获取了乌骨鸡黑色素细胞。通过观察各个培养阶段的细胞形态和细胞生长曲线,表明在专用培养基条件下,细胞增殖良好。根据细胞形态特征、电镜下的亚细胞结构、黑色素合成相关基因的表达分析、DOPA染色和细胞免疫化学染色鉴定,表明所获得的细胞符合黑色素细胞特征。细胞经传代后培养至第10代,仍保持了正常的生物学特性,说明所建立的培养体系可以实现乌骨鸡黑色素细胞体外原代培养。综上表明,本研究成功建立了乌骨鸡黑色素细胞体外分离培养体系。

Abstract:

The purpose of this study was to establish a method for melanocytes culture and identification system in vitro,and to provide an ideal biological material for investigating the melanocytes functions.Peritoneum of Silky Fowl was collected and digested by dispaseⅡ and trypsin-EDTA mixed digestive solution under different digestive time.The pure melanocytes were obtained after continuous passages.Through the observation of cell morphology and cell growth curve showed that the primary melanocytes grew well under the specific medium.The cell specificities were further confirmed by the morphology,ultrastructure observation under electron transmission microscope,genes expression associated with melanin synthesis,and cell characteristic by DOPA stain and immunocytochemistry.The successfully cultured melanocytes sustained the normal biological characteristics on passage 10 demonstrating that the culture of primary melanocytes was accomplished under this in vitro system.All together,the in vitro culture system of melanocytes from Silky Fowl was successfully established in our study.
